Well, you got it wrong i think :)
public static String fileExtension(File f) {
String name = f.getName();
int idx = name.lastIndexOf('.');
if (idx == -1) return null;
if (idx == name.length()-1) return new String("");
return name.substring(idx+1, name.length())); // that was what you got
wrong :)
}
public static string fileBaseName(File f) {
String name = f.getName();
int idx = name.lastIndexOf('.');
if (idx == -1) return name;
if (idx == 0) return new String("");
return name.substsring(0,idx); // that was what you got wrong :)
}
Now I hope I didn't make any mistake!
Best regards,
